' FASTENING-INSERTING MACHINE.

Application filed April 17, 1919. Serial No. 290,651.

To all whom it may concern:

' Be it known that I, FRED L. MACKENZIE, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Fastening-Inserting Machines, of which the following description, in

connection with the accompanying drawings, is a specificatiomlike reference characters on the drawings indicating like parts in the several figures.

This invention, relates to fastening inserting machines and more particularly to machines of this class which provide means for feeding the work and for locating fastenings with respect to the work during fastening inserting operations.

The invention is illustrated in connection with a machine designed to secure together two pieces of work, as, for instance, a heel section and a half sole wherein the heel sec- 7 tion is of different material from that pres ent in the half sole, and in which the sections or'pieces of work have been beveled edges adapted to be arranged in overlapping relation so' that ,fastenings driven through the overlapped edges will effectively secure the pieces together in such manner that the line of union between the pieces will be inconspicuous. ,It will be understood how ever that the invention may have other ap- 1 plications and uses.

' It. is an ob ect"of.the invention to provide improved feeding means for the work, the feeding means being preferably constructed and arranged to clamp the work firmly during the insertion of each individual fastening- 7 In one aspect the invention resides in means for inserting fasteningsinto work comprising clinching means for the fasten- 1 ings in association withwork feeding means located at each side ofthe clinching means softha't .the'work, whether of one or more pieces,fis properly fedand the fastenings accurately. inserted alongthe desired line. In

the work. feeding 1neans".'iscarried by the work support and'is'movable therewith as thefsufpportl li'soperated alternately to approachand.recedejfroni the work operating instiunientalit'ies;

tening to permit of unobstructed feeding of the work. In a practical form of the invention, the gaging means is so arranged as to move wit-h the feeding means in withdrawing from gaging position.

Other objects and features of the invention will appear from the following detailed description and will be pointed out in the claims.

In the drawings, F g. 1 1s avlew'in side elevation of one embodiment of the lnvention;

Fig. 5 is a detail of the operating means In the illustrative machine the fastening" inserting means may be and preferably is of the type of fastening. inserting mechanism shown in Patent No. 1,016,930,-granted Feb. 13, 1912, onan application filed by 5 lw illiam H. Borden.

The means for presenting the work to,the

fastening inserting means comprises in thev construction shown in a worksupport designated generally by the reference" character" 10 and consisting of apost' 12Iarrangedffo'r vertical movement in' guides or bearing members 14: attached to or integral 'Witha frame 16. Normally the work support is urged into work clamping relation with the to the main shaft 62 of the machine.

the post and the treadle. With the work in position on the work support the machine may be thrown into operation upon depress-v ing the treadle 28 which is pivoted at 30 to the frame 16 of the machine and has attached thereto at 32 the lower end of the rod 34, the latter being connected at its upper end to operate the shifting mechanism for the clutch by which the loose or power pulley 36 is caused to engage the fixed clutch member 38 on the main shaft of the machine. Upon rotation of the main shaft the power means for-operating the work support is actuated in timed relation with the insertion of fastenings by the fastening inserting means. In the illustrative embodiment of the invention the power means for operating the work support comprises wedge members 40 of which only one is shown in Fig. 1 of the drawings, the other being exactl similar and located to engage a roll on t e other side of the post 12 located in line with the roll 42' with which the wedge 40 co:operates in lifting the work support to clamp thework during the insertion of fastenings. As shown, the wedge 40 is slidably arranged in guideways 44 and 46 attached to or integral with the frame 16 of the machine. The means pro.- vided for operating the wedges 40 comprises preferably a bell-crank 48 fixedly secured to a shaft 50 mounted in a bearing or bracket 52 at the front of the machine frame. It should be understood that the other end of the shaft 50 carries an arm rigidly attached thereto-and connected to the other wedge 40 to operate the same simultaneously with the operation of member 40 as disclosed in Fig. 1. Mounted in a bearing 54 at the upper end of the machine frame is a bell-crank having an arm 56 car rying a roll 58 arranged to run in a face cam in the cam member 60 fixedly attachpld T e other arm 64 of the ll-crank mounted in the. bearing 54 extend laterally from the bearing and has rotatably mounted in its free end a member 66 through which passes freely the upper end of a rod 68 which has 1ts lower end pivotally attached to the arm 70 of the bell-crank 48. Surrounding the rod 68 between the member 66 and the adjustable collar 72 is a spring 74. It will be clear that upon rotation of the main shaft 62 the bell-crank comprising the arms 56 and 64 will be oscillated and through the connecting rod 68 cause corresponding rangers oscillation tr the bell-crank and thus actuation of the wedges 40.. Since the 'rod 68 passes freely through the member 66 at the outer end of the arm 64., bell-crank 48 will be yieldingly actuated through the spring 74 which surrounds the rod 68 between the member 66 and the collar 72. However, the work support will be lifted toclampthe work firmly against the nozzle 22 because of the action of the wedge mem bers 40 provided with relatively long wedging surfaces as indicated at 76.

The work supporting means 10 comprises in the construction shown an anvil member 7 8 carrying an anvil having'a flat fastening-clinching surface located directly in line with the fastening guiding nozzle 22 as shown in the drawings. To provide for adjustment of the anvil, its carrying member '2' 8 is provided with slots 82 through which pass bolts 84 to secure the member 78' to the bracket 86 of the work support 10, a screw or bolt 88 being provided'to adjust the member 78 after which it may be secured in adjusted'position by'tightening the bolts 84. Means is provided for feeding'the work across the anvil in the intervals of fastening insertion, the said means comprising preterably a feed roll 90 mounted on a bearing extending laterally from the upper end of the post bracket 86. While the feed roll 90 may be considered operatively asone memher, it is preferably made of two separatefeed rolls or disks 94 secured together by screws or bolts 96, there being interposed between the disks a ratchet wheel 98 presentlyto be described. The feed rollconsidered as a single member is provided with a circumferential groove 100 for the accommodation of the anvil 80 as disclosed in Fig. 4

0t the-drawings. Means is provided for intermittently rotating the feed roll 90, the said means in the present instance consisting of an arm 102 carried on'a pivot 103 extending through the bearing for the feed roll 90. A pawl 104 arranged to project between the feed rolls or disks 94 into engagement with the ratchet wheel 98 is carried by arm 102, the pawl being held in engagement with the ratchet wheel by 'means of a spring 106, secured at one end to a pin 108 on the pawl and at its other end to a second pin 110 on the arm 102. It will be" arrangement being such that as the bellcrank 48 is operated to cause forward movement of the wedges 40 the arm 118 is moved in the reverse direction about the pivot point 50 to cause a turning movement of the arm 102' in such a direction that the pawl 104 slides over the teeth on the ratchet wheel 98, movement of the ratchet wheel under these circumstances being prevented by a retaining member 120 (Fig. 2) the operative end of which engages the teeth of the ratchet just back of the point of engagement of the pawl with the ratchet. Upon rocking movement of the bell-crank 48 in a direction to withdraw the wedges 40 from below the rolls 42 the work support is permitted to descend from position in which the work is firmly clamped to a position in which the work is yieldingly clamped through the action of the spring 18. Vvhen this movement of the bell-crank 48 takes place the arm 118 moves in the reverse direction about the pivot point 50, that is, in a forward direction to cause the arm 102 to move to the right in Figs. 1 and 2 with the result that the pawl 104 in engagement with the teeth of the ratchet wheel 98 causes rotation of the ratchet wheel and consequently a feeding operation upon the work engaged by the feed wheel 90. In order that the extent of the feeding movement may be varied as desired, the connection of the link 112 with the arm 118 is adjustable, the adjustment in the construction disclosed being provided for in a curved slot 122 along which the pivot 116 may be adjusted and secured in adjusted position. If desired a scale may be applied along the edge of the slot 122 to indicate the lengths of individual feeding movements of the feed roll in accordance with adjustment of the pivot 116 along the slot 122. By'the means just described it is possible to predetermine the spacing between fastenings iiiserted in the work as the latter is] fed antomatically below the fastening inserting means.

In order that the work may be properly positioned for the insertion of the first fastening, gaging means is provided preferably in the form of a gage member 124 which is pivoted loosely on the pivots for the arm 102 and the feed wheel 90, and in the construction shown comprises a work engaging portion and two limbs 126 which are arranged to embrace the feed wheel 90. In order that the gage may be displaced after the insertion of the first fastening, it is held yieldingly in operative position preferably by neans of a spring 128, an extension 130 on one of the limbs 126 being engaged by a stop 132. It is clear that from the construction shown the gage is controlled by the work in such a manner that upon withdrawal of the work at the end of fastening insertion operations, the spring automatically returns the gage to operative position wherein the gage functions as a stop to locate the point of insertion of the first fastening in the work. As the work is fed automatically the gage is displaced laterally out of the way of the work and in the construction shown this is accomplished through the pivoting of the gage on the axis of the feed roll so that the gage moves laterally and downwardly with the feed roll and is held in yielding engagement with the surface of the work until the end of the fastening inserting operations when it is immediately returned to operative position by the spring 106. It is desirable to be able to predetermine the spacing of the first staple with respect to the edge of the work and especially since pieces of work vary considerably in size and more particularly in width. Moreover, in those cases in which the spacing between fastenings is changed for any reason whatever, it is desirable to space the first fastening with respect to the edge of the work in accordance with the predetermined spacing between fastenings. For this reason the gage 124 is made adjustable as to its gaging position by means shown as consisting of an arrangement in which the stop 132 is adjustable. This adjustment being accomplished by providing a screw-threaded bolt to function as a stop, the bolt being secured in adjusted position by means of a lock nut 134.

Other features of the work support which contribute to the ease and safety of operation of the device are found in a guard presently tobe described and in means arranged to co-operate with the feed roll 90 in the feeding operations, the said'means consisting of a roll or rolls 136 mounted preferably one on each side of the fastening guiding nozzle 22 to turn freely on pivots attached to the nozzle or made integral therewith. These rolls are preferably so mounted as to be in vertical alinement with corresponding portions of the feed roll 90 located upon the other side of the plane of the work. The operation of the machine is illustrated in connection with the securing together of two pieces of work which have their edges beveled so that they may be brought into overlapping relation, the pieces of work being located in the same plane. In operating on work of this nature it is ob-'. viously advantageous to have two rolls above arranged to co-operate with corresponding feed rolls below or on the other side of the work so that both pieces of work will be properly controlled and fed by the feeding means. Since the lower feed rolls are secured together and operate as one roll it is clear that the two pieces of work will be fed simultaneously and as one piece of work so that there is no tendency for displacement of two pieces of work relatively to each other during the fastening inserting operations."

j In thus spacing the feeding means'for the two pieces of workthere is provided room for the anvil or clinching means to operate to clinch the fastenings driven through the anvil together constitute the work support,

it is clear that the bracket 86 of the work support 10 could be extended to provide work supporting surfaces on one or both sides of the lower feed roll, and thus much larger pieces of work might be presented to the machine than could readily be handled without the aid of suchsupporting surfaces.

As now shown, the work support is designedto support the work only adjacent the line of inserted fastenings, the operative holding the outer ends of the pieces of work and findingit particularly easy to pass the work through i the machine since there is no obstruction on either side of the feed wheel to interfere with free movement of the work and of the hands. Preferably, the work support 10 carries a guard member 138 to prevent the hand from coming into accidental contact with the teethof thefeed wheel 90.

In operating the machine, the operative may select a single piece of work into which fastenings are to be driven, or two pieces in overlapped relation or ,two pieces of work having beveled edges, in the present instance a'heel part and a half-sole part, and place them with their edges overlapping in. engagement with the edge gage 12l,,it being necessary to depress the work support by the treadle 24: in order that the work may be in-' troduced and pressed by the work support yieldingly against the work engaging means on fastening guiding nozzle 22, which in the construction shown comprises. the rollers 136. Thereafter the operative depresses the treadle 28 starting the machine, whereupon the work is automatically fed step by step through the fastening inserting plane with the result that fastenings are inserted in the workin' predetermined spaced relation, thus securing thetwo parts of the work together.

As heretoforestated the gage is displaced downwardly and rearwardly at the beginning of the feeding operation so that there 1s no interferencewith-proper feeding to secure the desired spacing offastenings.
